Abstract: 1401620 Hydrocarbon conversion catalysts SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 15 Aug 1972 [17 Aug 1971] 38525/71 Heading B1E [Also in Division C5] Catalysts comprising a sulphide of Ni, Co, Mo and/or W are made by treating a composition comprising a porous carrier, a watersoluble salt of Ni, Co, Mo and/or W and water with a hydrogen sulphide-containing gas at a temperature below 150‹C and subsequently heating up the material in a hydrogencontaining gas to a final temperature above 200‹C. The amount of water in the composition to be treated with the hydrogen sulphidecontaining gas corresponds to the amount present in the composition after drying in a dry gas at 110‹C + 20-120% of the amount which the dried composition can absorb in the pores of the carrier at 20‹C. The composition to be sulphided may be prepared by impregnation in one or more steps either with drying after each step, the drying after the last step being controlled to give the correct water content, or when each impregnation uses a volume of solution substantially equal to the pore volume of the carrier with drying after each step except the last. The hydrogen sulphide - containing gas may be pure H 2 S or H 2 S+H 2  and the hydrogen-containing gas may be H 2 S+H 2 .

Patent GB-901788-A (GB)
Title: Improvements in and relating to time base generators
IPC: H01G9/22
Filed: 1959-11-27
Abstract: 901,788. Electrolytic devices. UNION CARBIDE CORPORATION. Nov. 27, 1959 [Nov. 28, 1958], No. 40323/59. Class 40 (9). A time base generator comprises an electrolytic cell using a solution of reversible redox system, e.g. iodine-iodide, which operates as an integrator and is associated with a changeover switch to enable the integrated state to be cleared. The electrolyte is contained in two compartments joined by a capillary and has three distinct concentration zones. The first zone is of variable concentration and is an " integral " zone between a common anode C and a read-out electrode R. An intermediate " dilute " zone lies between the read-out electrode and a shield electrode S, and a " reservoir " zone of high concentration is between the shield electrode and an input electrode I. As shown, a bias potential B2 is applied between the shield S and input I electrodes, and a bias potential B1 is applied between the read-out R electrode and either the common C or the input I electrode, depending on the position of switch S1. A constant current input from a source B3 having a magnitude determined by the value of a resistance 16, 18, or 20 selected by a switch S2 is applied to the input I and to the common electrode C when switch S1 is in one position. At the same time the bias B 1 is also connected to the common electrode and integration operation takes place. The output current through an ammeter 12 and resistor 14 is a measure of the solution concentration in the integrating zone. In the absence of an input signal this solution concentration remains constant and a constant output current is obtained, iodine being reduced to iodide at the read-out electrode R and iodide oxidized to iodine at the common electrode C. Increase of the solution concentration and hence increase of output current is obtained when a current is passed between the common and input electrodes, this increasing current being the required time-base waveform. The condenser 22 is normally omitted, and if provided requires the use of a varying, e.g. exponential, input signal. The output circuit is shunted by a resistance 10 having a negative temperature coefficient so as to provide temperature compensation. The time-base waveform is terminated by moving switch S1 to the second position (as shown), the input being then disconnected and the bias B1 applied between read-out and input electrodes so that the solution concentration in the integral zone is reduced. The integrator is thus cleared for a second operating cycle. A resistor 15 is included in the circuit of switch S1 to reduce the effects of switch change-over. Specification 901,787 is referred to.

Abstract: 1,203,817. Rotary drum filters. ENVIROTECH CORP. 29 Aug., 1968 [21 Sept., 1967], No. 41225/68. Heading BID. The rotor of a drum filter (which may be of the travelling endless band type, Fig. 1, not shown) has its cylindrical surface formed of impervious moulded arcuate segments 36 which are imperforate and provide a drainage deck. As described, the surface of the segments is formed with axial ribs 42 which support the filter cloth and whose grooves 41 constitute the drainage deck. Ribs 42 are not radial but are instead normal to the segment chord, to facilitate moulding in plastics. Adjacent segments are bolted together at holes 39. Filtrate drains along grooves 41 and enters an arcuate channel 49 in the head plate 47. (There is one channel 49 per segment 36). From there it travels radially inwardly along conduits constituted by matching grooves 54 in facing discs 47, 48, which together constitute one head plate. (The other head 33 is plain). Filtrate thus emerges through a corresponding trunnion duct 53. Fig. 1 (not shown) discloses a manually adjustable tensioning roller (68) for the endless filter band.
